无序纳米颗粒链中的等离子体激元:局域化和输运

Plasmons in disordered nanoparticle chains: Localization and Transport

Felix Rüting

摘要:

在偶极模型中研究了无序对金属纳米颗粒链中等离子体激元耦合的影响,考虑了两种类型的无序:颗粒形状的波动和位置的波动。在本征模和系统的输运行为中都发现了典型的局域化效应,并对局域化长度进行了估计。有人认为,链与故意引入的障碍构成有前途的系统,研究本地化效应的电磁波在光学频率下良好的可控和可操纵的条件下。

英文摘要:

Disorder-induced effects on plasmon coupling in chains of metallic nanoparticles are studied within a dipole model, by considering two types of disorder: fluctuations of the particles' shapes and fluctuations of their positions. Typical localization effects are found both in the eigenmodes and in the transport behavior of the system, and an estimate of the localization length is made. It is argued that chains with deliberately introduced disorder constitute promising systems for studying localization effects of electromagnetic waves at optical frequencies under well controllable and manipulable conditions.
